About 150 Delta flights in the US canceled after systems outage

About 150 flights of Delta Air Lines in the U.S. were canceled and some others were delayed on Sunday on account of an IT systems outage, the airline reported.

Delta said more flight cancellations were expected.

The IT systems outage at Delta is the latest of a number that have affected airline operations recently.

Delta reported earlier that its teams were working to fix quickly a systems outage that has resulted in departure delays and cancellations. It did not provide information on the systems issue that had caused the outage.

“Not all delays and cancellations are being reflected on Delta systems, including delta.com, the Fly Delta App, airport information screens or through our Reservations agents,” the airline said. It reported at 11:45 p.m. EST that a ground stop had been lifted.
